Description

  The present invention relates to an attachment part for attaching an electrical component to an electrical device and a blower device to which the electrical part is attached using the attachment part.

  Some electrical components attached to electrical equipment such as a blower are vulnerable to water and may cause tracking failure or rusting of metal parts when wet. In an air blower as shown in Patent Document 1, electrical components may be exposed to rainwater or condensed water that falls down. As described above, the electrical components that are vulnerable to water may be housed and attached in a housing box having a drainage structure at the bottom as shown in Patent Document 2.

  In the air blower as shown in Patent Literature 1, an electrical component is attached to an attachment component attached to the side surface of the apparatus main body. The mounting component is mounted in a state where the mounting surface for mounting the electrical device is lifted from the side surface of the electrical device by mounting legs having strip-shaped flat portions that are substantially perpendicular to the side surface of the main body of the blower device on the upper side and the lower side. There is no direct rain or condensation on the electrical components, and the electrical components may get wet with the water that falls along the sides of the body. Therefore, using a storage box as shown in Patent Document 2 is not advantageous in terms of cost. In the case of the above-described mounting parts, the path to the water electrical parts is only the upper mounting legs or the lower mounting legs when the mounting angle of the blower is changed. It is sufficient that the drainage structure shown in Patent Document 2 can be adopted for this mounting leg, but the mounting leg must be enlarged in order to construct such a drainage structure. If the drainage structure is configured with the size of the mounting leg as it is, there is a problem that the strength of the mounting leg is impaired.

  The present invention attaches to the side surface of the electrical equipment body as described above, with the mounting surface on which the electrical equipment is mounted floating from the side face of the electrical equipment by the mounting leg having a strip-shaped flat portion on the upper side that is substantially perpendicular to the side surface of the body. It is to avoid the arrival of water to the mounting surface without incurring a cost increase, and to obtain a blower device that can prevent the electrical component provided with the mounting component from getting wet. .

  In order to solve the above-mentioned problems, the present invention is such that at least the upper side is attached in a state where the mounting surface is lifted from the side surface of the electric device by the mounting leg having a belt-like flat portion that is substantially perpendicular to the side surface of the electric device. With respect to the mounting part to which the electrical part is mounted, a means is provided in which acute notches are provided on both sides of the flat part of the mounting leg, and a water guide hole that squeezes in a funnel shape on the back side in the plane of the flat part.

  According to the present invention, the mounting leg that supports the mounting surface in a state of floating from the side surface of the electrical device, which can be a route to the electrical component of water, is provided with an acute cutout and a water guide hole that squeezes into a funnel shape. Therefore, the water droplets on the flat portion lose surface tension due to the notch, become wet, are guided to the water guide hole, and are discharged from the water guide hole. Therefore, water does not reach the mounting surface to which the electrical component is attached. That is, even without providing a storage box or the like that completely prevents the ingress of water droplets, it is possible to avoid the arrival of water on the mounting surface with only a protective cover that prevents direct exposure to water droplets and dust.

  The mounting component of the present invention is mounted on the side surface of an electrical device (for example, a blower such as an air conveying fan in which propeller fans are arranged in a straight line), and is used to mount an electrical component such as a quick connection terminal. The attachment parts are made of sheet metal, and at least the upper side is attached to the side surface of the electric device, and the attachment surface is attached to the side surface of the electric device by a mounting leg having a belt-like flat portion forming a right angle. A similar mounting leg is provided on the lower side, and the mounting surface is supported in a diagonally floating state from the side surface of the electrical device. The electrical component is attached to the mounting surface. With respect to this mounting part, triangular notches with triangular angles are provided on both sides of a plane portion of the mounting leg located on a plane which is substantially perpendicular to the mounting surface. In the plane of the flat portion closer to the mounting surface than the cutouts on both sides, a water guide hole is provided on the back side.

  According to the present invention, the mounting surface that can be a path to the electrical component of water, the mounting leg that supports the mounting surface floating from the side surface of the electrical device, an acute notch, and a funnel-like shape toward the back side near the mounting surface The water droplets that are formed on the side surfaces of electrical equipment and formed on the flat surface of the mounting leg of the mounting parts lose their surface tension due to the notches on both sides, and are in a wet state. And is smoothly guided to the water guide hole and discharged from the water guide hole. Therefore, water does not reach the mounting surface for mounting electrical components, and even if there is no storage box that completely prevents the ingress of water droplets, only the protective cover that prevents direct exposure to water droplets and dust can be used. Even if not, the arrival of water to the mounting surface can be avoided.

Embodiment 1 FIG.
FIG. 1 is a perspective view showing a mounting part of the present embodiment, FIG. 2 is a perspective view showing the main part of the mounting part in an enlarged manner, and FIG. 3 is an enlarged main part of the mounting part in the mounted state. FIG. 4 is a perspective view of the blower, and FIG. 5 is an enlarged perspective view of a main part of another embodiment of the mounting part.

  The attachment part 1 of this embodiment is attached to a side surface 3 of a blower 2 such as an air conveying fan in which propeller fans are arranged in a straight line, and attaches an electrical part 4 such as a quick connection terminal. Raindrops and condensed water droplets may be generated on the side surface 3 of the blower 2. The attachment part 1 is made of sheet metal, and two attachment legs 5 are provided diagonally on the upper side and the lower side, and the attachment surface 6 on which the electric part 4 is attached is diagonally formed by the attachment legs 5. The device floats from the side 3 of the device. The free end side of each mounting leg 5 is bent at a right angle as the mounting portion 7 and screwed to the side surface 3 of the blower 2. With respect to the mounting part 1, a triangular notch 9 and a water guide hole 10 are provided on both sides of a plane portion 8 located on a plane that is substantially perpendicular to the mounting surface 6 of the mounting leg 5 as a drainage structure. . The water guide hole 10 is configured as a hole that swells in a funnel shape on the back side in the plane of the flat portion 8 closer to the mounting surface 6 than the notches 9 on both sides (see FIGS. 2 and 3). It is easier to obtain the strength of the mounting legs 5 by providing the notches 9 and the water guide holes 10 in a shifted manner than when they are provided side by side in the width direction of the mounting legs 5.

  According to the present embodiment, the notch 9 having an acute angle and the mounting surface 6 on the mounting leg 5 that supports the mounting surface 6 in a state of floating from the side surface 3 of the blower 2, which can be a path to the electrical component 4 of water. Since the water guiding hole 10 that swells in the form of a funnel toward the back side is provided closer to the rear side, the water droplets generated on the side surface 3 of the blower 2 and the like and formed on the flat portion 8 of the mounting leg 5 of the mounting part 1 are: The surface tension is lost by the notches 9 on both sides, and the surface becomes wet and is smoothly guided to the water guide hole 10 and discharged from the water guide hole 10. Accordingly, water does not reach the mounting surface 6 on which the electrical component 4 is mounted, and even without a storage box or the like that completely prevents the ingress of water droplets, it is possible to prevent direct exposure to water droplets and dust, as shown in FIG. With the protective cover 13 alone, it is possible to avoid water reaching the mounting surface 6 without increasing the mounting leg 5.

  As the drainage structure, as shown in FIG. 5, a trap groove 11 extending in the entire width direction may be provided in the flat portion 8 of the mounting leg 5, and a drain hole 12 may be provided at the groove bottom of the trap groove 11. In this case, since the water droplets are collected in the trap groove 11 only by the trap groove 11 and do not perform the trap function, the drain hole 12 is necessary. In this configuration, there is almost no configuration that impairs the strength of the mounting leg 5, and the trap groove 11 becomes a rib, which can rather contribute to an improvement in strength.
